[syslinux] ONTIMEOUT LOCALBOOT -1 and menu.c32 -- Solution: "ONTIMEOUT .localboot -1" works!

[Harald_Jensas at Dell.com]

Hi,

I just found this post:
http://syslinux.zytor.com/archives/2005-September/005814.html

ONTIMEOUT was broken in menu.c32, and you fixed it. But the fix broke support for LABEL references in ONTIMEOUT.

I changed my "ONTIMEOUT local" to "ONTIMEOUT .localboot -1" and it works!

Anoying is that I tried ONTIMEOUT LOCALBOOT -1 before. This failed, but after having a look at the source code seeing that you compare the kernel arg to ".localboot" I figured that might be it. And it was... :)

My entire config follows:

DEFAULT menu.c32
PROMPT 0
TIMEOUT 50
ONTIMEOUT .localboot -1
MANU TITLE LiveCD Boot Menu

LABEL linux
	MENU DEFAULT
	MENU LABEL Linux Live CD
	KERNEL linux
	APPEND initrd=initrd.igz 

LABEL local
	MENU LABEL Boot Local HardDrive
	LOCALBOOT -1


Cheers
Harald

Hi,

Yes, somthing is wrong. :)
And it is menu.c32 that cause the problem.

If I let menu.c32 laod and count down, it fails. Just reloads the menu and starts a new countdown.
If I ESC from the menu to get a prompt and wait until timout it works.
If I press TAB and it lists ".localboot -1" and press ENTER it works.
If I do not load menu.c32 it also work.
If I change "ontimeout" to point to a lable that should load the linux from CD and I get the same result.

It is only the combination "ontimeout", "PROMPT 0" and "menu.c32" loaded that fails.

I can imagine menu.c32 has it's own timout code? And possibly eaven it's own ontimeout code?
I can imagine the problem will be there, and how menu.c32 sends commands back to ISILINUX?

I use ISOLINUX 3.11 and the menu.c32 from the syslinux-3.11 package from kernel.org.

I also tried with ISOLINUX.BIN and menu.c32 from the syslinux-3.20-pre3 from kernel.org and I get the same problem.


Is there any way I can help give more information?



Best Regards
Harald Jensås

It should.  Clearly something is wrong.
